DRYS B. F. SKINNER was the "father" of modern behavioral analysis using his "Skinner Box" to show the results of various reinforcement patterns getting rats to press a bar to get a food pellet. He found that the pattern that got the best responses was actually an intermittent pattern where the desired behaviour (in our case buy the stock) was inconsistently (intermittently) reinforced (in our case a huge run up in the pps). The stock chart shows a clear intermittent reinforcement pattern. Everyone is betting on the timing of the next pps pop (food pellet).
